Non Hazardous Replacement for N-Propyl Bromide
Q: What can we do to replace n-propyl bromide? We are cleaning grease and oil from stainless steel. We had heard Citranox might do the job well.
A: The compound n-propyl bromide is often used in vapor degreasing and is considered to be associated with some serious health risks and is hazardous. We would certainly recommend you switch to a drain-safe, biodegradable, aqueous detergents.
How to: Making detergent solution (1%) by weight or volume
Making detergent solution (1%) of powdered detergent such as Alconox or Tergazyme, you can make your solutions by weight or by volume.
Defining Free Rinsing Detergent
A non-free rinsing cleaner might contain fragrances that were designed to deposit and leave a fresh scent, or it might contain corrosion inhibitors that are designed to deposit and leave behind an anti-corrosion film.
Alconox, Inc, cleaners are free rinsing detergents and do not leave deposits on substrates after rinsing.
Cleaning Vitamin Residues
Q. We manufacture vitamins, which include minerals (calcium, magnesium etc.) and have found that Citranox is very effective in cleaning the residue left in our equipment. Unfortunately, we have learned that the pH of Citranox is too low for our local requirements. Do you have another detergent with a higher pH that would work equally as well?
Dilution Precision in Concentration Measurements
Q. Do I determine detergent dilution by weight or by volume or both?
A. In a laboratory setting, the most common method is to either make a weight/weight dilution (10-20 g Alconox detergent in 990 g of water), or a weight/volume dilution (10-20 g Alconox in 990 mL of water) for 1-2% solutions. In manufacturing situations, often directions are written volume/volume or volume/weight.
